Light Intensified Fiber Optic Sight

ABSTRACT

A method and apparatus providing for the enhancement of the brightness of a fiber optic sight. Whereby the fiber optic sight is enhanced by way of any number of lenses used to focus ambient light onto the fiber optic cable.

FIELD OF THE INVENTION

The application relates to a method and apparatus for improving the luminosity of a fiber optic sight, particularly through the use of a magnifying lens.

BACKGROUND OF THE INVENTION Prior Art

Shooters often utilize luminous sights to help aim their weapons, particularly at night or in environments with compromised levels of light. Tritium or fiber optic sights are especially common amongst handgun users. Fiber optics sights work by gathering ambient light and transmitting it out the ends of the fiber. With varying environments, however, the quality and availability of ambient light can be so lacking as to render fiber optic sights ineffective or even useless. By increasing the amount of ambient light that flows into the length of the fiber, one can increase the amount of light emitted by the ends of the fiber. Fiber optic sights do not have limited lifetimes or require specific power sources. Tritium sights operate by utilizing the light released by the radioactive decay of the element tritium, a controlled substance in the United States. As a controlled substance, usage of tritium in products necessitates certain legal precautions, particularly with regard to acquisition, production, and disposal, which users of fiber optic sights need not observe. The potential volatility and the nature of its status as a controlled substance make tritium a less favorable form of optical illumination than fiber optic sights.

Because fiber optic sights require an abundance of ambient light flowing into said sights in order to be useful, fiber optic sights tend to be ineffective in environments with limited or compromised availability of ambient light. Focusing currently available ambient light onto fiber optic cables used for sighting mechanisms can improve the illumination provided by such fiber optic sights.

There exists a need for a method to increase the amount of ambient light that is directed at the length of an optical fiber such that the ends of said optical fiber may increase in luminosity.

Objects and Advantages

Accordingly, several objects and advantages of this invention are:

-   -   (a) To allow for the possible increase in the amount of ambient         light entering the fiber optic cable;     -   (b) To allow for the possible increase in luminosity of the         fiber optic sights;     -   (c) To allow for the possible increase in effectiveness of the         fiber optic sights;     -   (d) To allow for the possible increase in the accuracy of the         shooter.

Further objects and advantages of this invention will become apparent from a consideration of the drawings and ensuing description.

DETAILED DESCRIPTION FIGS. 1-4, 6

With reference now to the drawings, the preferred embodiment of the light intensified fiber optic is herein described. As can be seen in FIG. 1, according to certain embodiments of the prior art, iron sights 10 are used to indicate to the shooter an estimated trajectory for the weapon's discharge. Iron sights 10 often are positioned atop the weapon in such a way that, as a shooter aims the weapon and looks down the iron sights 10, iron sights 10 will line up with the target (not shown). Iron sights 10 generally do not provide any illumination, and if they do, such illumination is only cursory for the purpose of distinguishing the iron sights 10 from the weapon itself.

As can be seen in FIG. 2, according to certain embodiments of the prior art, tritium rod 17 lies within housing 10. The combination of a plurality of tritium rods 17 and housings 10, combine to form a plurality of tritium sights 31. Tritium sights 31 are, according to certain embodiments of the prior art, positioned atop the weapon in such a way that, as the shooter aims the weapon and looks down the tritium sights 31, tritium sights 31 line up with the target (not shown), such that tritium sights 31 are used to indicate to the shooter an estimated trajectory for the weapon's discharge.

As can be seen in FIG. 3, according to certain embodiments of the present invention, fiber optic rod 12 lies within housing 11, and opening 13 is configured such that opening 13 allows for light to enter optic rod 12. Opening 13 allows for an increased amount of light to enter optic rod 12 because, as can be seen in FIG. 3, optic rod 12 has more light available to it. According to certain embodiments, configuration of opening 13 around or about optic rod 12 shall provide for more light to be concentrated on optic rod 12 than should optic rod 12 be completely encased in housing 11.

As can be seen in FIG. 4, according to certain embodiments of the present invention, fiber optic rod 12 lies within housing 11, and lens 14 is configured such that lens 14 allows for light to enter optic rod 12 and, according to certain embodiments, enhances or increases the amount of light entering optic rod 12. The enhancing or increasing of the amount of light entering fiber optic rod 12 makes fiber optic rod 12 brighter. According to certain embodiments, the configuration of lens 14 shall provide for more light to be concentrated on optic rod 12 than should only opening 13 be configured around or about optic rod 12.

As can be seen in FIG. 6, according to certain embodiments of the present invention, fiber optic rod 12 lies within housing 11, and a plurality of lenses 14 are configured such that the plurality of lenses 14 allow for light to enter optic rod 12 and, according to certain embodiments, enhance or increase the amount of light entering fiber optic rod 12. According to certain embodiments, the configuration of a plurality of lenses 14 around optic rod 12 shall provide for more light to be concentrated on optic rod 12 than should only one lens 14 be configured around optic rod 12.

The invention may be embodied in other forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

OPERATION FIGS. 1-4, 6

As can be seen in FIG. 1, according to certain embodiments of the prior art, iron sights 10 are used to indicate to the shooter an estimated trajectory for the weapon's discharge. Iron sights 10 often are positioned atop the weapon in such a way that, as a shooter aims the weapon and looks down the iron sights 10, iron sights 10 will line up with the target (not shown). Iron sights 10 generally do not provide any illumination, and if they do, such illumination is only cursory for the purpose of distinguishing the iron sights 10 from the weapon itself. The shooter will line up the iron sights 10 with the target (not shown) to aim the weapon.

As can be seen in FIG. 2, according to certain embodiments of the prior art, tritium rod 17 lies within housing 10. The combination of a plurality of tritium rods 17 and housings 10, combine to form a plurality of tritium sights 31. Tritium sights 31 are, according to certain embodiments of the prior art, positioned atop the weapon in such a way that, as the shooter aims the weapon and looks down the tritium sights 31, tritium sights 31 line up with the target (not shown), such that tritium sights 31 are used to indicate to the shooter an estimated trajectory for the weapon's discharge. As the tritium gas within tritium rods 17 undergoes radioactive decay, it emits glowing light from tritium rods 17 such that tritium sights 31 provide extra illumination. Because tritium sights 31 provide illumination, the shooter can aim the weapon even in limited or compromised light environments.

As can be seen in FIG. 3, according to certain embodiments of the present invention, fiber optic rod 12 lies within housing 11, and opening 13 is configured such that opening 13 allows for light to enter optic rod 12. Opening 13 allows for an increased amount of light to enter optic rod 12 because, as can be seen in

FIG. 3, optic rod 12 has more light available to it. According to certain embodiments, configuration of opening 13 around or about optic rod 12 shall provide for more light to be concentrated on optic rod 12 than should optic rod 12 be completely encased in housing 11. As an increased amount of light enters optic rod 12, optic rod 12 becomes brighter. The combination of a plurality of optic rods 12 and a plurality of housings 11 combine to form a plurality of fiber optic sights 15. Fiber optic sights 15 are, according to certain embodiments of the present invention, positioned atop the weapon in such a way that, as the shooter aims the weapon and looks down fiber optic sights 15, fiber optic sights 15 line up with the target (not shown), such that fiber optic sights 15 are used to indicate to the shooter an estimated trajectory for the weapon's discharge. As fiber optic sights 15 provide illumination, the shooter can aim the weapon even in limited or compromised light environments.

As can be seen in FIG. 4, according to certain embodiments of the present invention, fiber optic rod 12 lies within housing 11, and lens 14 is configured such that lens 14 allows for light to enter optic rod 12 and, according to certain embodiments, enhances or increases the amount of light entering optic rod 12. The enhancing or increasing of the amount of light entering fiber optic rod 12 makes fiber optic rod 12 brighter. According to certain embodiments, the configuration of lens 14 shall provide for more light to be concentrated on optic rod 12 than should only opening 13 be configured around or about optic rod 12. The combination of a plurality of fiber optic rods 12 and a plurality of housings 11 combine to form a plurality of fiber optic sights 15. Fiber optic sights 15 are, according to certain embodiments of the present invention, positioned atop the weapon in such a way that, as the shooter aims the weapon and looks down fiber optic sights 15, fiber optic sights 15 line up with the target (not shown), such that fiber optic sights 15 are used to indicate to the shooter an estimated trajectory for the weapon's discharge. As fiber optic sights 15 provide illumination, the shooter can aim the weapon even in limited or compromised light environments.

As can be seen in FIG. 6, according to certain embodiments of the present invention, fiber optic rod 12 lies within housing 11, and a plurality of lenses 14 are configured such that the plurality of lenses 14 allow for light to enter optic rod 12 and, according to certain embodiments, enhance or increase the amount of light entering fiber optic rod 12. According to certain embodiments, the configuration of a plurality of lenses 14 around optic rod 12 shall provide for more light to be concentrated on optic rod 12 than should only one lens 14 be configured around optic rod 12. The combination of a plurality of fiber optic rods 12 and a plurality of housings 11 combine to form a plurality of fiber optic sights 15. Fiber optic sights 15 are, according to certain embodiments of the present invention, positioned atop the weapon in such a way that, as the shooter aims the weapon and looks down fiber optic sights 15, fiber optic sights 15 line up with the target (not shown), such that fiber optic sights 15 are used to indicate to the shooter an estimated trajectory for the weapon's discharge. As fiber optic sights 15 provide illumination, the shooter can aim the weapon even in limited or compromised light environments.
